4. The method of claim 1, wherein the characterization of Doppler variations in the particular cell is a linear approximation quantified by a Doppler rate.

5. The method of claim 4, wherein adjusting the local frequency reference over time according to the characterization of Doppler variations in the particular cell comprises periodically adjusting the local frequency reference over time according to the Doppler rate.

6. The method of claim 5, wherein the local frequency reference determines a downlink receive frequency of the UE.

9. The method of claim 1, wherein obtaining the characterization of Doppler variations in the particular cell comprises receiving the characterization of Doppler variations in the particular cell via a connection configuration message, a handover command, system information, or a paging message.

11. The method of claim 10, wherein an uplink transmit frequency of the UE is based on the ideal frequency reference.

12. The method of claim 10, wherein adjusting the local frequency reference over time according to the characterization of Doppler variations in the particular cell comprises adjusting the local frequency reference over time based on the adjusted relative Doppler shift adjustment factor.

13. The method of claim 1, wherein the wireless network is a Non-Terrestrial Network.

14. The method of claim 1, wherein the network node is a terrestrial base station, a non-terrestrial base station, or a gateway for a non-terrestrial base station.

15. The method of claim 1, wherein the characterization of Doppler variations within the particular cell is pre-calculated.

16. The method of claim 1, further comprising performing timing correction at the UE based on information related to timing drift.

17.
